This invention relates to machines for operating on lasts. The invention is herein illustrated as embodied in a machine for disassembling the parts of separable lasts of the type in the use of which a forepart and a heel part are held together in assembled relation within a shoe by means comprising interengaging bonding devices and a latch, the latch being releasable from within the jack pin thimble hole of the heel part of the last, and the bonding devices being disengageable after release of the latch to disconnect the last parts and to eflect separation or disassembly of those parts by relative tilting and sliding movements thereof so that the last may subsequently be removed from the shoe. A last of this general type is described and claimed in a co-pending application, Serial No. 386,034, filed August 15, 1929, in the name of G. P. S. Cross, the last disclosed in that application being characterized by having a latch which is shaped like a hook and which is mounted for tilting movement in directions heightwise of the last between engaging and disengaging positions.

'One object of the present invention is to provide a machine which will be especially adapted for disassembling the foreparts and heel parts of separable lasts of the type disclosed in the application above referred to, although in various aspects the invention is not limited to machines for use in connection with that particular type of last.

l Vith this object in View, one feature of the present invention consists in the provision, in a machine for disassembling the foreparts and heel parts of separable lasts of the type having interengaging bonding elements and means for locking the bonding elements in interengaged relation, of relatively movable members for rigidly holding one of the last parts and for releasing the locking means, and means for thereafter relatively moving the last parts to disengage the bonding elements. In the illustrated machine, a jack pin is movable heightwise of the last to co-operate with a fixed abutment to clamp the heel part of the last and to release a latch to unlock the bonding elements of the last. Also, as herein illustrated, the means for relatively moving the last parts is operated first to tilt the forepart of the last to disengage one set of bonding elements and thereafter to slide the last forepart while maintaining it in tilted position to disengage the other set of bonding elements. Thus there is provided a machine for disassembling the foreparts and heel parts of separable lasts having means for rigidly holding the heel part of such a last, and means for moving the forepart of the last relatively to the heel part to disengage'the bonding elements of the last, such an organization constituting a further feature of the present invention. I

The invention further consists in various features of construction and combinations and arrangements of parts hereinafter described and claimed.

The machine shown in the drawings is designed to operate upon a separable last A which .is shown in detail in Figs. 2, 10 and 11 and which is substantially like the last disclosed in the co-pending application Serial N 0. 386,034, hereinbefore mentioned. Brief- 1y described with reference to the figures above specified, the last A comprises a forepart B and a heel part C which are adapted to be firmly secured together while the last is in use and to be entirely separated one from the other to facilitate the insertion of the last in a shoe or the removal of the last from a shoe. The means for securing together the forepart and the heel part'of the illustrated last comprise a hook latch D and two sets of bonding elements, one set being indicated at E and the other set at F. The bonding elements E are adapted to be engaged and disengaged by relative heightwise sliding movement of the last parts B and C. When the last parts are assembled, however, relative sliding movement thereof for the purpose of disengaging the bonding elements E is resisted by the interengagement of the other set of bonding elements F and the elements F can be disengaged only by relative tilting or rotational movement of the last parts about a transverse horizontal axis. The latch D, however, normally prevents such relative tilting of the last parts and thus serves ,to lock the bonding elements in interengaged relation. To disassemble the last parts, therefore, the latch D must first be tripped and thereafter the last parts must be first relatively tilted about a transverse horizontal axis and thereafter relatively slid in a direction heightwise of the last. The latch D is hooked or notched at G to engage and lock together two plates H and I which are fixed to the forepart B and the heel part C, respectively, of the last and which carry the bonding elements E and F. The latch D is adaptedto be tripped by a rocking or tipping movement and a tailJ on the latch projects into a thimble hole K in the heel part of the last so that a properly shaped tool or jack pin can press against the tail J, and thus trip the latch D so as to release the plates H and I preparatory to disassembly of the last parts.

For a more detailed description of the con-- struction of a separable last of the type herein shown and for a more thorough understanding of the manner of assembling and disassembling the parts of the last, reference may be had to the co-pending application Serial No. 386,034 hereinbefore mentioned.

The illustrated machine is designed to operat-e upon a separable last of the type briefly described above, while the last parts are assembled and secured together within a shoe, to trip the latch D and to disengage both sets of bonding elements of the last so that the last parts may be readily removed from the shoe. For this purpose the illustrated machine comprises a vertically movable jack pin 14 which functions to support a last which is to be operated upon and to trip thelatch preparatory to disengagement of the bonding elements, a fixed abutment 16 for engageing the heel of a shoe on the last, a downwardly movable abutment or shoe-bottom-engaging pad 18 for tilting the forepart of the last to disengage the bonding elements F, and an upwardly movable post 20 which is engageable with the cone of the last for sliding the last forepart upwardly to eifect disengagement of the bonding elements E.

The above-mentioned parts are supported by a frame comprising a casing 22 which surmounts a hollow pedestal 24. The fixed abutment 16 consists of a jaw formed at the upper extremity of a bracket 26 which is bolted to one side of the casing 22, the abutment aw 16 having a horizontal lower surface for engaging the tread surface of the heel of a shoe,

such as the shoe X shown in the drawings, on thelast which is to be operated upon. The jack pin 14 is raised to move the heel of the shoe into engagement with the abutment 16 and also to move the sole of the shoe into engagement with the abutment or pad 18 by mechanism actuated by a foot treadle 30 (Fig. 1) which is pivoted at 32 to the base of the pedestal 24. The treadle 30 also actuates mechanism for moving the pad 18 to tilt the forepart of the last in the shoe X and to raise the post 20 to slide the forepart of the last upwardly relatively to the heel part.

The ack pin 14 is provided with a. laterally projecting lug 34 the upper end of which is constructed and arranged to engage the tail of the latch D in the last and upon upward movement of the jack pin to trip the latch so as to permit the above-described tilting and sliding movements of the last forepart to take place. At its lower end the jack pin 14 is pivotedat 36 to a post 38 which is vertically slidable in a bearing 40 formed in a turntable 42 carried by a post 44 which is journaled in the casing 22. The lower portion of the jack pin 14 is reduced in diameter, as indicated at 46, thus providing sufficient clearance between the jack pin and the bearing 40 on the turntable to permit a slight tilting of the ack pin about the pivot 36. This provia.

sion for limited tilting movement of the jack pin 14 enables a last on the jack pin to tilt slightly as may be necessary to insure engagement of both the heel and forepart portions of the bottom of a shoe on the last with the abutment 16 and pad 18 respectively and insures engagement of the shoe bottom with the pad 18, irrespective of the size or amount of forepart spring in the particular last being ope-rated upon. A spring 48 confined in a socket in the post 38 tends to tilt the ack pin 14 toward the abutment 16. The turntable 42 is countersunk within a recess in the top of the casing 22 and is held in the recess by means of a nut 50 on the lower endof the post 44. A spring 52, secured at one end to the turntable 42 and at the other end to the casing 22, normally holds the turntable in the radial position indicated in Fig. 5, this position being determined by engagement of a pin 51 on iii) the turntable with one end of a slot v53 in the casing 22. A key 54 fixed to the post 38 and slidable in a keyway 56 in the bearing of the turntable permits vertical sliding movement of the post 38 and the jack pin 14 but prevents axial turning of these parts relatively to the turntable 4 A shoulder 58 is adapted by engagement with the upper end of the key 54 to limit upward movement of the jack pin so as to prevent the jack pin from being accidentally withdrawn from the turntable when a last and shoe is being removed from the machine.

A last, the parts of which are to be disassembled, is placed upon the jack pin 14 while the jack pin and the turntable 42 oocupy the positions indicated in Fig. 5, the last being positioned at this time as indicatedby the dotted lines X in Fig. 4. Thereafter, the turntable is rotated by manually turning the last and shoe from the dotted line position X to the full line position X, thus moving the heel of the shoe into position beneath the fixed abutment 16 and the forepart of the shoe into position beneath the movable abutment pad 18 and above the post 20. Upward movement of the jack pin 14 for the purpose of moving the shoe into engagement with the abutment 16 and the pad 18 is effected by means of apush rod which is mounted for vertical sliding movement in a bearing 62 in the casing 22, the jack pin post 38 having been brought into vertical alinement with the push rod60 by the rotation of the turntable 42 from the positionshown in Fig. 5 to the position shown in Figs. 4 and 6. r

The means for operating the push rod 60 to raise and lower the jack pin comprises a lever 64 one end of which is pivoted at 66 to the push rod 60 while the opposite end of the lever 64 is forked at'68 to straddle an actuator in the form of a vertical slide rod 70 (Fig. 7) which is mounted in a suitable way 21 in the casing 22. The slide rod 70 is pivotally connected at 72 with the upper end of a treadle rod 74, the lower end of which is pivoted at 76 (Fig. 1) to the treadle 30. The forked end 68 of the leverr64 is located between an adjustable collar 78 on the slide rod 70 and the lower end of a bushing 80 which is normally clutched to the slide rod 70 for vertical movement in unison with the slide rod. The lever 64 is fulcrumed at 82 against the lower extremity of a lug 84 de pending from the top of the casing 22, the lever being held yieldingly against the lug 84 by means of two springs 86 secured at their upper ends to the lug 84. This con struction permits the lever 64 to rock about the lower end of the lug 84 for the purpose of raising the jack pin to engage the shoe with the abutment 16 and the pad 18, and thereafter, during continued downward movement of the slide rod 70 for purposes hereinafter to be described, thesprings 86 yield, permitting the lever 64 to rock idly about its pivotal connection 66 .as a fulcrum.

The means for clutching the bushing 80 to the slide rod 70 comprises a ball 90 (Fig. 8) confined within a hole 92 in the side of the bushing 80 and normally engaging also within a notch 94 in the side of the slide rod 70. Normally, the ball 90 is held seated in the notch 94, thus connecting the bushing 80 with the slide rod 70 so that it is constrained to move downwardly therewith. After the slide rod 70 and the bushing 80 have been moved. downwardly a distance suflioient to raise the jack pin 14 the required amount, the ball 90 is brought into a position opposite a notch 96 formed in a fixed bearing sleeve 97 in the casing 22 in which the bushing 80 is slidably mounted. At this time the flanged upper extremity 81 of the bushing 80 engages the casing 22 and further downward movement of the bushing is prevented. Continueddownward movement of the slide rod 70 within the bushing 80, however, forces the ball 90 ordJwardly in the hole 92 into engagment with the notch 96 in the fixed sleeve 97and out of engagement with the notch 94 in the slide rod, thus releasing the bushing 80 from the slide rodand enabling the slide rod to continue its downward movement without imparting further movement to the lever 64.

WVhen the machine is idle the slide rod 7 0 is locked against downward movement to prevent accidental starting of the machine by means of a horizontally slidable lock bar 100 (Figs. 4 and 6) mounted in a slideway in the upper portion of the casing 22, the lock bar extending from the slide rod 70 to the turntable 42and having at one extremity a conical surface 102 adapted to engage a correspondingly shaped socket 104in the slide rod 70 and at the opposite end a conical surface 106 adapted to engage within a correspond ingly shaped socket 108 in the periphery of the turntable 42. l/Vhen the turntable is occupying the position indicated in Fig. 5 the socket 108 is located out of alinement with the/lock bar 100 and the lock bar is main tained at the right-hand limit of its sliding movement, with the conical surface 102 en gaged within the socket 104 in the slide rod, thus locking the slide rod against movement. When the last has been moved into the full line position indicated at X in Fig. 4, thus moving the turntable into the position indicated in Fig. 6, the socket 108 in the periphery of the turntable is brought into alinement with the lock bar 100. Thereafter, upon depression of the treadle 30 the conical su1'- face 102 on the lock bar will be forced out of the socket 104 in the slide rod 70 and the slide rod thus released ward movement. The movement of the look bar caused by downward movement of the for further down treadle and slide rod 70 engages the conical surface 106 on the slide rod with the socket 108 in the turntable, thereby locking the turntable to hold the last in the horizontal angular position indicated by full lines at X in Fig. 5 throughout the'operation of the machine. .After the last parts have been disassembled, however, and the treadle has been released, the resulting upward movement of the slide rod finally returns the socket 104 into alinement with the lock bar and thus unlocks the turntable so that the last may be returned into the dotted line position X preparatory to removal of the last from the jack pin.

The post 20 is adapted to be raised and lowered through connections with the slide rod 7 O. The post 20 is raised simultaneously with the raising of the jack pin 14 for the purpose of moving a pad 116 at the upper end of the post into engagement with the cone of the forepart of the last. Thereafter the pad 18 is rocked downwardly to tilt the last forepart to disengage the bonding elements F, after which the post 20 is raised still higher for the purpose of sliding the last forepart upwardly to disengage the bonding elements E.

The connections between the post 20 and the slide rod 70 for raising the pad 116 into contact with the cone of the last forepart comprise a lever 118 one end of which i forked as indicated at 120 to embrace the slide rod 70 while the opposite end of the A lever is pivoted at 122 to the lower extremity of the post 20. After the forepart of the last has been tilted by the downward. mov ment of the pad 18 the post 20 is raised an additional amount to slide the forepart of the last upwardly by means comprising a lever 126 secured to a rockshaft 128 which is ournaled in the bearings formed in the sides of the casing 22. The lever 126 is forked at its rear end, as shown at 130 (Fig. 7) to embrace the slide rod 7 O and it is arranged to be actuated in one direction by means of a collar 132 adjustably secured to the slide rod 7 0 above the lever 126 and in the opposite direction by means of a collar 134 adj ustably secured upon the slide rod 70 below the lever 126. The front end of the lever 126 is notched at 186 to receive the rounded rear extremity of a nipper bar or clutch 138 the forward extremity of which is received in a slot 140 formed in the side of a sleeve 142 on the post 20. The nipper bar 138 is pivoted at 144 to the sleeve 142 and is formed with an eccentric or cam face 146 adapted to be cramped against a flattened surface 148 on the post 20 by actuation of the lever 126, thereby to clutch the sleeve 142 to the post 20 so that the post 20 may be raised by the lever 126. Normally however, the sleeve 142 is supported by means of a lever 150 in such a position that the sleeve 1 will be unclutched from the post 20 leaving the latter free to be raised by the lever 118 independently of the lever 126, the nipper bar 138 and the sleeve 142. v

The upward movement of the post 20 for the purpose of engaging the pad 116 with the cone of the last is a movement of varying am plitude depending upon the size of the particlar last which is being operated upon. Consequently, the connections for imparting this initial upward movement to the post 20 must be so constructed as to takeup any overmotion of the actuatingmeans. As shown, the lever 118 is actuated from the lever 64 through a push rod connection 152, theupper end of the push rod 152 being received in a socket in the rear arm of the lever 64, and the lower end of the push rod being received in a socket in the rear portion of the lever 118. Downward movement of the rear arm of the lever 64 is transmitted through the push rod 152 to the lever 118, rocking the lever 118 about its pivotal connection 154 with the lower end of a link 156 the upper end of which is pivoted at 158 to the lever 150. The lever 150 is pivoted at 151 and is forked at its front end, as shown at 160, the forked extremities of thelever being curved upwardly to engage lugs 162 on the sleeve 142 and thereby normally to support the sleeve 142. A spring 164 fixed at its upper end to the casing 22 and secured at its lower end to the forward portion of the lever 150 serves normally to maintain the lever in position to support the clutch sleeve 142, this position being determined by engagement of the lever with an adjust-able stop screw 165. The strength of the spring 164 sufiicient to support the pivot 154 upon which the lever 118 is fulcrumed so that during the first part of the movement of the lever 64 the lever 118 will be rocked by the push rod 152 about the pivot 154 as a fixed fulcrum. The lever 118 will rock about the pivot 154 until the upward movement of the post 20 is arrested by engagement of the pad 116 with the last. Thereupon the pivotal connection 122 between the lever 118 and the post 20 becomes the fulcrum about which the lever 118 is rocked and by the action of the push rod 152, the lever 118 being swung downwardly about the fulcrum 122 sufiiciently so that the link 156 will lower the lever 150 towithdraw the support of its forward portion from the clutch sleeve 142. Thereupon, the weight of the sleeve 142 becomes supported entirely by the nipper bar 188 and the lever 126, thus causing the nipper bar to grip the post 20 thus clutching the sleeve 142 to the post. The post 20 is now ready to be raised positively by the action of the lever 126 when the latter is engaged and rocked by the collar 1 2 on the slide rod 70.

Before the post 20 is raised as just described for the purpose of sliding the last forepart, however, the forepart of the last of a lever mounted for rocking movement tact with a cam 180 fixed on a rockshaft 182 upon a rod 172 and having a downwardly extending curved arm 174 carrying a cam roll 17 6 at its lower extremity. v A spring 118 is mounted to maintain the cam roll 17 6 in conjournaled in brackets carried by the casing 22. An arm 184 also fixed to the rockshaft 182' is received between upper and lowershoulders 186 (Fig. 3) formed on a sleeve1 8 which is mounted with provision for sliding movement on the slide rod 70 below a collar 190 wich is adjustably fixed to the upper end of the slide red. A spring 192 secured at its lower end to a bracket on the casing 22 and at its upper end to the cam 180 normally holds the cam in the position shown in Fig. 2 and, through the arm 184, holds the sleeve 188 in engagement with the collar 190. The sleeve 188 is al o normally held in the position shown in Fig. 2 by means of a latch 194 pivoted at 196 to the sleeve 188, the upper hooked end of the latch engaging a lug 200 on the collar 190. Normally, the latch is held in engagement with thepin 200 by means of a spring 202. A tail 204 on the latch is adapted to engage a fixed but adjust-able abutment 206 (Fig. 2) on the casing to trip the latch for purpose hereinafter to be explained.

As the slide rod 70 moves do-wnwardly,the

cam 180 is rocked upwardly and when the rise 210 on the cam engages the cam roll 17 6 the lever carrying the pad 18 is rocked in a direction to tilt the forepart of the last an amount suthcient to disengage the bonding elements F. Approximately at this time the post 20 is raised for the purpose of sliding the last torepart upwardly for the purpose of dis engaging the bonding'elements E During,

this upward movement of the post 20 and the resulting upwardsliding movement of the last forepart it is desirable to maintain the last forepart in substantially its initial tilted relation relatively to the heel part of the last;

To accomplish this result, provision is made for gradually raising the pad 18 at sub stantially the same rate of speed as the post 20 is moved upwardly; This movement of the pad is permitted and controlled by the port-ion 212 of the cam 180. While the portion 212 of the cam 180 is operated to control the upward movement of the pad 18, the post 20 (together with the pad 116) is being raised by the lever 126 acting through the nipper bar 138, the lever 126 being actuated by the collar 132 on the slide rod 70.

As the treadle 80 approaches the lower limit of its movement the pawl 194 is tripped by engagement of the tail 204 with the abut ment 206, thus disconnecting the sleeve 188 from the collar 190 so as to permit the slide forepart of the last from the heel part so that the last parts may be manually separated after the shoe and last have been removed.

from the machine. To permit removal of the shoe and last from the machine the operator releases the treadle 30 whereupon a spring 216 (Fig. 1) connected with the treadle returns the slide rod 7 0' to its normal elevated position, and through the connections hereinbefore described with'the jack pin 14 and the post 20 the jack pin is lowered to relieve the pressure between the heel part of the shoe and the abutment 16. Upon the upward movement of the slide rod the collar 134 engages the forked rear extermity of the lever 126, rocking the lever in a direction to lower the sleeve 142, together with the post 20, until one of the lugs 162 on the sleeve 142 engages a lug 218. on a. latch 220 the upper end of which is pivoted at 222 to the casing 22 and the lower end of which is acted upon by a spring 224 arranged to normally urge the latch220 in a direction to move the lug 218 into the path of movement of the correspond ing lug 162 on the sleeve 142. Downward movement of the sleeve 142 is thus positively arrested and inasmuch, as further rocking movement of the lever 126 is prevented by engagement'of the notched arm of that lever with afixed abutment 226 (Fig. 7) the nipper bar 138 is actuated to release the sleeve 142 from the post2O so that the post, togetherment with the lock bar 100, thus permitting the lock barto slide in a direction to release the turntable 42 to permit, the shoe and last to be removed from the machine. At this time the pad; 18 is exerting only a light preserator then grasps the'shoeand turns it to move the heel and forepartportions from beneath the abutment-16 andpad 18 respectively, and then removesthe last from'the jack pin. As the forepart of the shoe is swung out from beneath'the pad 18 the lug 2 18is rocked downwardly by the spring 192 and the pad 18 is returned to its normal positionby the action of the spring 178 w en the treadle '30 isfin its fully lie pressed position a pin 230 projecting from the front end of the lever 118, by engagement with a cam surface 232 at the lower protion' of the latch 220, swingsthe latch upwardly a.
